heres the two main things i know about the differences in a G model engine versus the E model engine other than what the rear wheel is driven by, the E model has a roller bearing crankshaft versus the G having a plain bearing crankshaft, and the E model has a larger intake camshaft than the G.
I know I know I shouldn't put money into this bike but i think the only person that will be able to stop me is me, so id just like to know the best route going through with this, I plan on holding onto this bike for a very long time, possibly forever as its my first and also I spent twice the amount of money I bought it for learning how to fix it so this bike would never give me the money back I put into it regardless.
the plan is to do a big bore kit bringing it from 670cc to 740cc, doing an intake mod and correctly tuning the carbs for the air increase, and completely going through the motor aswell as everything else to make sure I dont have any trouble down the road for a very long time since every little bit will be gone through all at once, id rather pay my dues now all together than little by little since i use this bike so much.
i read back on an older post i put up and seen that the G model engine does make a little bit less horsepower than an E model and im sure the chain drive does have something to do with it but also having a larger intake cam does allow more air whether it being a taller or wider lobe, so i was thinking of putting an E model cam to help the motor breathe more.
i guess my questions are would an E model camshaft be a direct fit onto the G motor, also would i be able to do the same to the exhaust cam or is that something that doesnt matter, and also would it be a better idea to go for a an E model crank or would that not help with anything performance wise. if theres a set of cams from a larger GS that could help increase power that would also be something nice to be informed about.
i plan on completely tearing this motor down as the bike is going to be mechanically restored, i cant do the top end and add more power without making sure the bottom end is going to be okay.
